6. Our approach
7. Going Forward

3.
 Different media and information sources
 Strongly emerging participatory culture
 Collective knowledge and intelligence of
society

4.
 People
 Things
 Events

5.
Documents, Data, Events
 Document created by Humans.
 Text, Music, Movies
 Data collected by Humans
 Photos, Audio, …
 Events happen.
 Most documents describe events and objects in those.
 Most data is collected for events.

6.
 Facebook, Twitter, Google +, …
 Sensor networks
 Billions of sensor getting connected
 Ambitious projects
 Planetary Skin by Cisco and NASA
 Smart Planet by IBM

7.
 Can things in real world be connected to other
things?
 Does this even make sense?

8.
 Five Senses connect us to the world.
 We use our sensors (vision, audio, …) to
experience the world.
 Sensors could be the interface between the
Cyberspace and the Real World.
 Sensors are placed for ‘detecting events’.
 How do you decide what sensors to put at any
place?
 Would you put a sensor if nothing interesting ever
happens at a place?

 Data
 Objects
 Relationships and Events

11.
 Objects -- popular in the West.
 Relationships and Events – popular in the
East.
 Objects and Events – seems to be the new
trend.
 The Web has re-emphasized the importance
of every object and event being connected to
others -- East Meets West.

12.
 Consider a Web in which each node
 Is an event
 Has informational as well as experiential data
 Is connected to other nodes using
 Referential links
 Structural links
 Relational links
 Causal links
 Explicit links can be created by anybody
 This EventWeb is connected to other Webs.

13.
 SN are web-based services that allow individuals to:
 construct a public or semi-public profile within a bounded system,
 articulate a list of other users with whom they share a connection, and
 view and traverse their list of connections and those made by others
within the system.
 The nature and nomenclature of these connections may vary
from site to site.

 All traditional Persistent Web sources
 Micro blogs
 Status updates
 Tweets
 Streams
 Micro Events
 All sensors ‘Chirping’
 Internet of Things
 People input in any form

27.
 Result of
 Exponential growth in connectivity
 Sensor Networks
 Evolution of Sharing Culture
 Technology for Collective Knowledge

28.
 Each Micro-blog:
 What’s on your mind?
 What’s happening?
 Share What’s New …
 Really an event reported by Humans.
 Can associate experiential data along with
information.
 Time and location can be associated.

29.
 Billions of disparate kinds of sensors being
placed everywhere.
 Each sensor detects ‘basic events’ and
broadcasts it in a simple form.
 Develop a system to process these micro-events
and make them useful.

30.
 ‘Chirps’ could be of different types
 Define behaviors like:
 Heavy traffic
 Popular event going on
 People leaving X area
 Violence starting
 ...
 Use for Macro-behvior analysis

 From Micro-behavior to Macro-behavior
 Studied in many fields:
 Economics
 Thermodynamics
 Systems Biology
 Web facilitates this for many novel applications

34.
 Divide space (world) into small Pixels of
appropriate size.
 Assume that each event is a particle of a specific
type. Create a Social Image for specific type of
events.
 A time-ordered sequence of these emages will
be similar to a video representing spatio-
temporal changes in events of that type.

1. For centralized agencies
 Most of what we have done so far
2. For individuals who subscribe
 Asthma
3. Alerts based on (implicit subscription): user’s
(FB) interests, events attending, trips, sports,
music, fan pages…
 Maybe we can derive asthma, from FB details?
4. I’m bored! What’s around me? (based on a
generic interest set)
 NowLedger
